Phenotypical segregation among female rat hypothalamic gonadotropin-releasing hormone neurons as revealed by the sexually dimorphic coexpression of cholecystokinin and neurotensin.

Abstract excerpt

The neuroendocrine control of the gonad is exerted primarily by the gonadotropin-releasing hormone neurons located in the septum and the hypothalamus. Despite their sexually dimorphic activity, tonic in males and phasic in females, these neurons have not appeared qualitatively different between sexes in intrinsic organization or chemical phenotype. Here, by using multiple-label immunocytochemistry, it is...
